A professional diver has captured what are believed to be the first pictures of a wild fish using a tool.
The picture shows a foot-long blackspot tuskfish smashing a clam on a rock until it cracks open, so it can eat the bivalve inside.
The authors of a scientific paper on the matter claim that this meets the definition of tool use first laid out by Jane Goodall in her work with chimps.
